I am running Dougs headers so oil filter size is a consideration. My brother in law has a trans dapt dual filter kit that he said I could have.. what do you think?

[tom s]

I don't like hoses in a engine compartment.I like to run the full length filter but if not room I run the shorter.I run either B9 or B39 Baldwin.Tom

[hgerhardt]

This is for a '64 A-body? You can use a Firebird long-branch oil filter adapter which angles the filter back along with the Firebird/Big Car 90deg adapter. I have this setup on my '66 GTO with Doug's headers.

In the pic below, I have an adapter plate which allows Chevy filters to be used on Pontiacs. You can just use a Baldwin B9 without an adapter.

Can you shed some light on that filter adapter plate your using? You made it, bought it, how it fits.


Thanks

If you are referring to the Long Branch, big car 421 engine, tilted adaptor or the Firebird long branch adaptor those were factory pieces on those cars. The adaptor was actually some special length bolts, a steel "blocker" plate, and the cast aluminum adaptor.

I do know people who have made adaptors to plumb the hoses to a remote filter and only one guy Bill Klausing (A Machinist) who built a tilted adaptor like the factory unit.

Better to go on EBay and do a search for that set of adaptor parts as the machining today would be very expensive to make it exactly like the factory parts.

While you made good comments, they had nothing to do with the question. Charles was referring to my Chevy filter adapter plate.
I made that adapter plate from 1/8" 6061-T6 and machined an O-ring groove in the face which seals on the Pontiac 90 or 110 deg adapter The ring slips over the threaded center tube. The center tube is plenty long enough to accommodate the 1/8" spacer.

If you want, send me a PM with your email and I'll send you a STEP file so you can get one made.

I still run a dual filter on the drag car and did run one on the street car for years.

On the street car, the Doug's headers along with the scatter shield prevents the oil filter (short or long) from being removed unless the complete adapter is removed and the adapter and filter lifted out towards the top. I didn't have the problem with the stock bellhousing and Dougs, but the scatter shield blocks removing just the filter. A newer skinny filter would possibly slip by, but just not that enamored with those.

The good point is the remote dual adapter has the filters running in parallel so the filter restriction is cut in half. The bad point is the complete dual filter assembly looses about six pounds of pressure mostly due to the hose runs.

The additional time and grief of removing the adapter is only once a year on the street car because I don't put that many miles on it. Still a royal pain though.

I guess your plans for the by pass filter are shelved then?

It just seems overly complicated and unsightly in an engine bay that I am working hard to keep neat. Do you have any pictures of your installation?

Okay, looks are more important than clean oil, gotcha.....

Tee the pressure line into the oil filter adapter where the oil pressure switch is located, run the return line to the oil filler cap to return it back to the engine, mount the filter bracket with 3 screws, yep overly complicated. If you can't install one in an hour, you shouldn't own tools......

One more thing, a video that pits a conventional oil filter against a by pass filter side by side. Watch the video, (2 minutes, 21 seconds) and tell me which filter does a better job of actually removing dirt, and cleaning the oil.........https://www.youtube.com/watch?v=AaBuV9pOcrU

And finally a picture of a Frantz filter installed on a big block mopar musclecar. You're right, that polished stainless is ugly. It probably should be mounted in the trunk, or behind the front bumper, where no one will see it. Which is entirely possible with a little extra line, if you want it completely out of sight. Also notice the small diameter lines used, compared to the lines twice the size that a remote filter uses.



You're correct, those 2 big remote filters will look much better under the hood, they won't clean the oil either........

Bet that looks even better when you removing the filter for an oil change..

As regards, fluid dynamics, twice the filter material area provides twice the filtration capacity as far as particulate removal. The working pressure might drop but would be offset by the dual filters' capacity to flow more oi. You have a volume vs. pressure trade-off. In the performance aftermarket, Pontiacs are an exception, using a high pressure pump instead of high volume due to the architecture limitations of the motor.

OP, I would put the dual remote filters on in a heartbeat. Use braided steel hose, good fittings and insulated sleeves around the headers. The hoses can be routed back to the firewall, restrained with clamps and routed around the exhaust to the fender well for peace of mind.

First of all you don't change oil, you change the filter. Oil stays in the engine because it doesn't get dirty. I change my oil every 3-4 years, 30-40,000 miles. The reason you have to change oil with a standard system is the inability of the filter to remove all of the contaminants, you have to drain all the stuff the filter can't remove.

When changing the filter media, leave the car sit overnight before you pull the canister off, and you get zero oil drip. It all runs back into the pan overnight leaving the media virtually dry. Since you can mount the Frantz in any position the owner in the picture could have easily mounted it bottom side up, or even sideways, makes no difference what position it's mounted at.

My diesel dually, and my 05 LS2 GTO have the filter mounted the exact same way the picture shows. As long as you leave it sit overnight you get no drips, toilet paper holds a lot of liquid.

A by pass oil filter system supplies zero oil to the internally oiled engine parts, the reason it can be restrictive, and filter oil to a very high standard. The standard full flow filter is kept intact and all the pressure oiled parts are oiled just as the factory designed it.

There are 2 separate filter systems, one to oil the engine parts, as always. One dedicated to cleaning the oil, and returning it to the pan.

Schematic of the 2 systems, and how they operate:

I doubt Dual Filters does anything else than less of a pressure drop through the filters. They certainly dont "filter better" than a single filter, just more volume.

I run a fullsize Wix filter on my car with Doug's headers, no issues on or off

[Tom Vaught]

1964 and 1967 frames should be very close.
I have a 1966 convertible Frame under my 1964 GTO Convertible.
Fit perfectly. Part # for the Wix filter you mentioned?

Tom V.

[67gtospud]

If I recall correctly it was Wix part number 51258

The 51258 is the shorter 4.338" long filter. The full length WIX # is 51049 which is 5.178" long.

The WIX filter lookup is excellent - giving all kinds of information on each filter.

https://www.wixfilters.com/Lookup/filterlookup.aspx

When working for the ACD, MTC and Mopar warehouse distributor before I retired, I worked with my WIX rep numerous times and he taught me how to use it.

You can enter most any brand oil filter # into the lookup and it will cross it to the WIX equivalent. You can also do a make/model/year lookup. It will find the oil, air, fuel and any other filter that WIX makes for that vehicle.

After you find the filter, if you click on the WIX filter #, it will take you to a pop up that has the full specs and if you click on "applications" it will show you every vehicle that used that filter.

Both of those filter #'s were used extensively by AMC/Jeep/GM as well as a number of boat and tractor applications.

THANK YOU VERY MUCH. Be safe out there.

i run the fram HP5 or KN HP-2003 with dougs 1.75 headers in a 79 firebird
no issues with either one
i did look at the dual remote filters, but will wait till i decide on the next engine upgrade
If i go remote i want one of remote filter adapters that use the large oil filter size like the Fram HP6a
